' The flexible. tube 1 5f is -preferably" of a gen position retains the bag "withinth'e and in" erally" flattened 'or "elliptical cross" section? as" plained, and this tube advantageously has a relatively thin wall The tube is preferably connected to the bag by a connection such as shown in Fig. 5, including a female socket member 23 carried by the bag at its lower end and a coupling member 24 which is adapted to screw into the socket member and which has alower end to which the upper end'of the tube is secured. The coupling member 24 is relatively short and it pref erably has a manipulating flange 25.

The shut-01f Hi can be of any preferred type, but it is understood that it is adapted to cooperate with a tube of the section shown in Fig. 9 in a manner to close off the flow of liquid through the tube. The interior opening of the tube is of such contour that, when the opposite, sides of the tube are pressed toward each other,

tube disposed in the bottom of the box body in a convenient manner, and the pipe placed in the lowermost part of the body, after which the lower lid is closed and fastened. This may be done conveniently after the upper lid has been closed and fastened. After the upper lid has been closed and fastened, the box may be inverted and-the parts conveniently disposed in what was previously the lower part. The pipe [1 has such length that'it can be easily placed in the box in the diagonal position of Fig. 8.

they will make contact with each otherthroughout the width of the tube so as to shut off the liquid.

At the lower end of the tube is carried a coupling member 26 to which the nozzle or pipe I! is connected by the usual screw connection.

The top or lid l2 of the box is hinged to the box body by suitable hinges 21, and folding braces 28 connect the lid with the box body, having a pivotal connection with each. The connection between the brace and the lid, generally indicated at 29, may comprise a small lug 30 struck out from the lid and serving to mount a pivot pin for the brace. When the lid is swung upwardly, so as to be at right angles to the box body, the lid, by virtue of its connections with the body through the hinges and the braces at the respective sides of the body, will serve tosup'port the box body in the position shown in Fig. 2, when the lid is supported upon the" wall or like support. Such support may be provided by a hook or nail (not shown) engaging a suspending aperture 3| which is provided in the lid. This aperture may conveniently be formed in the body portion of the lid near the edge which is remote from the hinge.

In the form shown, the lid or top cover [2 is provided with a flange 3| that extends along the sides and across the front. The lid is adapted to be fastened to the box body or bag support so that the lid can be held in the closed position of Fig. 4 when the article is not in use. complish this. In the example shown, the flange 3|- is provided at the front of the device with a projection or catch 32 adapted to snap over a projection 33 on the box body (Fig. 5). The

bottom lid or cover i3 is provided with a flange 34 similar to'the flange 3|, and this covering member can be held closed by providing it with a fastening projection 35 adapted to engage a projection 36 on the box body.

When the device is ready for use the .top lid, suitably attached to a support, holds the bag carrier at right angles to the supporting wall to.,which the top lid i'sattached, and the lower lid'or cover is in depending position alongside the wall, as will be evident from Fig. 5,. for example. The bag can then be filled with liquid and used in the customary manner. After use and removal of liquid from the bag, the device can be readily folded to'place it in condition within the lower part of the box body, and the Different means may be provided to aca few folds in the bag transversely of its length i are required ,to stow it in the box in a small space.

One of the advantages of using a tube 15 'of flattened cross section is that such a tube can be readily stowed within the box without the need of coiling it. The tube can be gathered up and stowed very easily, and it is not necessary. to arrange it neatly, as shown in Fig. 8. Its

turns or folds can be in confused or topsy-turvy arrangementwithout any harm being done so long as the tube is not caught between the lower cover and the body. I

It is also to be understood thatwhen the article is in the folded position, there is sufflcient room within the enclosure for additional articles in the way of accessories. It is understood from what has been said that the transition from the operative position to the transport position is very easy. and convenient. Conversely. it will be apparent that the operation of converting from the transport position to the operative position is easy and convenient; taking very little time. Obviously the opening of the lids can be'accomplished easily and quickly, and when the lower lid is released the bag will junfold of itself, carrying with it the tube. It is then only'necessary to fasten up'the top lid and apply the pipe. In the transport position the operative parts are securely enclosed and protected, and for packing the article is of convenient size and shape.

The body of the box serves as the form of an open frame in which the upper part of the bag is held. This is shown as a shallow member, but the dimensions disclosed are only by way of example. g Y I It is manifestly of advantage to be able'to store a principal part of the bag, togetherwith its attached tube, within the lower part of a carrying case. It is also manifestly of advantage to use a tube which does not require coiling, and which will fold and will not kink when stowed away with confused arrangement of the turns or folds. is also of advantage to employ a pipe, such-as a douche pipe, which is received and stored with the syringe tube in the lower part of they syringe case.

The folding braces between the top lid and the body serve to support the bag carrier effectively in a position in which the carrier extends substantially at right angles to the raised top lid.

In the form shown, the braces are formed of interpivoted links, and the two link of a brace are in alignment with each other when the box body and top lid are at right angles to each other; but other means may be adopted forthis general purpose. j Q

In' the form shown, the douche pipe I1 is slightly curved in an endwise direction, so as to a bag carrier in increase its capacity and yet enable it to be received in the case in a diagonal position.

While the enclosing case for the article is shown as constructed of metal, other material, such as plastic, may be used for this purpose. In any event, the case is preferably relatively rigidso as to serve as a protection for the contents. The case is shown asbeing of rectangular shape, but

' in certain aspects of the invention variation may be made in this respect.

The case not only protects the syringe parts but serves to prevent clothing and the like from coming into contact with moisture remaining on tangular box body, a foldable flexible bag supported within the box body so that it may depend from the lower end of the box body, cover means for the box body at the lower part thereof, hinged upper cover means for the box body, and folding brace means between the box body and said upper cover means for holding the box body in right-angular relation to said upper cover means and preventing dislocation of said box body when the device is supported from a supporting wall.

2. A device such as described, comprising a rectangular box body having upstanding end and side walls, a foldable flexible bag having a rectangular mouth within the upper portion of said box body, said bag being provided with through longitudinal openings at the front and rear edges of the bag mouth, and laterally rigid cross rods for said bag having their ends fastened in the side walls of the box body and having their bodies passing through said longitudinal openings,

3. A device such as described, comprising a rectangular box body, a foldable flexible bag supported within the box body so that it may depend from the lower end of the box body, cover means for the box body at the lower part thereof, hinged upper cover means for the box body, and folding brace means between the box body and said upper cover means for holding the box body in rightangular relation to said upper cover means and preventing dislocation of said box body when the device is supported from a supporting wall, said folding brace means including a link pivoted to the box body and a link pivoted to the upper cover means and said links having pivotal connection with each other.
